Bespoke and ex-stock

Resin systems are designed to protect and insulate printed circuit boards (PCBs) and electronic components from the threats of harsh and challenging environments, including; moisture, vibration, thermal or physical shock and general contamination. By encapsulating the entire device, resins can form a complete barrier against such environments offering superior performance under extreme conditions.

Potting and encapsulation resins also offer excellent mechanical protection. Mechanical protection can be identified in a number of ways; superior performance is evident in applications involving prolonged exposure or immersion in harsh chemicals, or those exposed to vibrational, thermal or physical shock, for example. The higher level of protection is achieved through the mass of the resin surrounding the unit. This is different for every
application however potting and encapsulating resins always provide a far more substantial covering than thatoffered by conformal coatings.

Due to the bulk of material surrounding the PCB, potting and encapsulation resins are commonly two-part systems which when mixed together form a solid, fully cured material, with no by-products. In cases where the conditions are not considered extreme, Electrolube offer a range of conformal coatings which provide a combination of protection in humid and corrosive environments with ease of application. They can be used for complete coverage or selective application onto the PCB, thus minimising the weight added as a result of applying a protective material.

Polyurethane

UR5638 Transparent LED Resin

250G - 5Kg

UR5638 is an optically clear / transparent polyurethane resin consisting of an aliphatic polymer designed to provide excellent UV stability while at the same time excellent transmission of the visible spectrum of light. This makes it an ideal choice for potting LEDs which operate in the visible light spectrum, in particular white LEDs.

It's a tough resin which offers excellent environmental protection for both indoor and outdoor LEDs - although it is ideally suited to potting larger units due to its low exothermic values.
